Mice metabolic cage CaloBox

modularindirect calorimetry

A novel system for the indirect calorimetry of mice, rats, birds, and other small animals. Simply connect the CaloBox with an animal cuvette, turn on air flow, and press “Start” for a measurement. Common applications are: Animal metabolism, nutrition, heat regulation, thermoregulation, bioenergetics, activity, animal behavior, energy balance, resting metabolic rate, energetics of locomotion, and many more. The Calobox automtically measures and calculates typical indirect calorimetry parameters such as metabolic rate, energy expenditure (EE), and respiratory exchange ratio (RER). Video introduction. The CaloBox was developed by Prof. Dr. Gerhard Heldmaier (Philipps-Universität Marburg, Germany). The PhenoSys CaloBox is a PhenoSys Collaboration product. These products are brought to market together with the scientists who developed them. The CaloBox is a joint product of Prof. Dr. Gerhard Heldmaier and PhenoSys. Internal pumps for air flow through animal cuvette 30..150 L/h Down to 4 sec reliable measurement interval No drying of sample or reference air required Measurement of O2 , CO2, and water vapor content in sample air; Comparison to reference air Automatic adjustment of gas sensors with reference air in preset intervals (zero adjustment) Calculation of metabolic rates: O2 consumption per unit time (V′O2 ) Carbon dioxide production (V′CO2 ) Water vapor evaporation (V′H2O) Respiratory exchange ratio (RER, RQ) Calculates energy expenditure (EE) based on V′O2 and RER
